Using du command to get disk space, but only wanted the value, without the path. I am able to print using awk, but how to store only the value into variable?
du -sh $path | awk '{print $1}'

du -sh $path
27G $path

`var=$(du -sh "$path" | awk '{print $1}'); echo "$var"` – Gilles Quénot May 11 '23 at 03:01

1Perl is overkill compared to awk for something so trivial but `... | perl -lane 'print $F[0]'` – Shawn May 11 '23 at 03:35

You could use a variable to capture and store the output of du command:
disk_space=$(du -sh $path | awk '{print $1}')
echo "$disk_space"

For robustness, [quote your variables](https://stackoverflow.com/questions/10067266/when-to-wrap-quotes-around-a-shell-variable), though, especially `"$path"` – tripleee May 11 '23 at 03:16
